Improving NoC Performance by Non-contention Ejection Architecture

In this paper, we propose a non-contention ejection architecture to improve the performance of Network-on-Chip (NoC). In this architecture, the contention is avoided by allocating a dedicated channel for every packet which may be ejected simultaneously, which make sure that packets in the network can be ejected promptly, and thus the number of packets stayed in the network is decreased and the communication performance is improved. Results show that compared with traditional ejection architecture, the proposed architecture improves the communication performance greatly with reasonable area increase.
